Join Team CASA today! Team CASA is people of all shapes, sizes, ages and fitness levels who walk or run at their own pace in various events in the Big Sur International Marathon to raise money for Court Appointed Special Advocates (CASA) of Santa Cruz County. CASA purchases registrations for selected BSIM events and offers them to participants at cost. The Team CASA participant creates a personilzed web page through FirstGiving.com to raise a minimum of $500 in sponsorship donations. Participants may also choose to self-sponsor with a personal donation at the goal level. This is one of CASA's most important fundraisers, bringing in more than $50,000 each year.
